BioLite’s new off-the-grid gear doubles down on power and light

BioLite released most of its 2017 product line today, spearheaded by the new and improved CampStove 2. All the products share common design features, centered around either battery improvements, expanded lighting possibilities, or both. Along with th...

NASA picks solar power candidates for deep space missions

NASA is going to need solar power if it wants to keep its future deep space missions running, and that means getting someone to build that light-gathering technology. Fortunately, the agency has some partners lined up. It just picked four solar pow...

BioLite’s latest gear includes a stove, lamp and a pair of solar panels

The smell of burning wood from pot belly stoves and fireplaces is noticeable in some Brooklyn neighborhoods during the winter, but down underneath the Manhattan Bridge overpass at BioLite headquarters it's business as usual. The company's been hard a...

Stanford researchers ‘cool’ sunlight to improve solar cell efficiency

A team of researchers from Stanford University have devised an ingenious means of boosting the efficiency of solar panels by exploiting a fundamental physics phenomenon. Solar panels lose efficiency as they heat up. Just as the top of your head rad...

Fraunhofer black silicon could catch more energy from infrared light, go green with sulfur

Fraunhofer black silicon could catch more energy from infrared light, go green with sulfur

Generating solar power from the infrared spectrum, or even nearby frequencies, has proven difficult in spite of a quarter of the Sun's energy passing through those wavelengths. The Fraunhofer Institute for Telecommunications may have jumped that hurdle to efficiency through sulfur -- one of the very materials that solar energy often helps eliminate. By irradiating ordinary silicon through femtosecond-level laser pulses within a sulfuric atmosphere, the technique melds sulfur with silicon and makes it easier for infrared light electrons to build into the frenzy needed for conducting electricity. The black-tinted silicon that results from the process is still in the early stages and needs improvements to automation and refinement to become a real product, but there's every intention of making that happen: Fraunhofer plans a spinoff to market finished laser systems for solar cell builders who want their own black silicon. If all goes well, the darker shade of solar panels could lead to a brighter future for clean energy.

Inhabitat’s Week in Green: ECOLAR house, transparent solar panel and Star Wars terrariums

Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.

Inhabitat's Week in Green Solar Decathlon Europe, transparent solar panel and star wars terrariums

For the past two weeks Inhabitat has been reporting live from the Solar Decathlon Europe in Madrid, where 18 student teams from around the world have been competing for the title of the world's most efficient solar-powered prefab house. As usual, suspense was running high in the final days of the competition, and we're excited to announce that Team Rhône-Alpes' Canopea House has been named this year's winner! The beautiful modular house took top honors in the architecture and sustainability categories, and it features a 10.7 kW photovoltaic array on the roof that produces more than enough energy to power the home.

Some of the other standouts at the Solar Decathlon Europe include Germany's ECOLAR House, which features a flexible, modular design that can expand or shrink to accommodate the needs of its owners. It came as no surprise that the German team was tops in the engineering category, and the team incorporated hemp insulation in the floors, walls and ceiling to prevent thermal loss. Team Andalucia's Patio 2.12 House, which consists of four separate prefabricated modules built around an interior courtyard, scored high marks for energy efficiency and innovation. And although Italy's MED in Italy House might not look like much on the outside, step inside and you'll enter a different world altogether. The highly efficient home features a central courtyard and a rooftop photovoltaic array that generates about 9.33 kWh of energy per year -- roughly double what it needs. Team Rome also added wall layers that can be filled with heavy materials to provide high thermal mass once the home is installed.
